From 613a76ff52a680e71db772306a260b9cb7f95b49 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 24 May 1996 20:16:39 +0000 Subject: Fri May 24 02:31:36 1996 Ulrich Drepper * sysdeps/unix/sysv/linux/speed.c: Add new speed value 460800. Thu May 23 23:09:33 1996 Ulrich Drepper * FAQ: Add answer for 100% source code compatibility to Linux libc by David Mosberger-Tang. Update from bind-4.3.4-T3B. * inet/arpa/inet.h: Add prototypes for inet_pton, inet_ntop, inet_nsap_addr, and inet_nsap_ntoa. * resolv/gethnamaddr.c: Correct compatibility problems (sprintf), remove fourth argument to inet_pton and correct handling of host_addr passing. * resolv/inet_ntop.c: Correct compatibility problems (sprintf). * resolv/inet_pton.c: Remove fourth argument. * resolv/resolv.h: Remove prototypes for inet_nsap_addr and inet_nsap_ntoa. Now on . * stdlib/gmp-impl.h: Add prototypes for internal functions. Thu May 23 22:49:15 1996 Roland McGrath * Rules (subdir_install): Remove dep on sor-$(subdir). (static-only-routines): Removed variable and associated rules. * sysdeps/unix/sysv/linux/alpha/Makefile (headers): Add sysdeps/alpha/bsd-_setjmp.S, sysdeps/alpha/ffs.S, sysdeps/unix/sysv/linux/alpha/sigsuspend.S, sysdeps/unix/sysv/linux/alpha/start.S, --- resolv/gethnamaddr.c | 27 ++++++++++++++++----------- resolv/inet_ntop.c | 10 ++++++++-- resolv/inet_pton.c | 21 ++++++--------------- resolv/resolv.h | 3 --- 4 files changed, 30 insertions(+), 31 deletions(-) (limited to 'resolv') diff --git a/resolv/gethnamaddr.c b/resolv/gethnamaddr.c index b80595b7d5..18f4764428 100644 --- a/resolv/gethnamaddr.c +++ b/resolv/gethnamaddr.c @@ -88,6 +88,12 @@ static char rcsid[] = "$Id$"; # include <../conf/options.h> #endif +#ifdef SPRINTF_CHAR +# define SPRINTF(x) strlen(sprintf/**/x) +#else +# define SPRINTF(x) sprintf x +#endif + #define MAXALIASES 35 #define MAXADDRS 35 #define MAXADDRBUFSIZE 8192 @@ -475,8 +481,7 @@ gethostbyname2(name, af) * Fake up a hostent as if we'd actually * done a lookup. */ - if (inet_pton(af, name, host_addr, - sizeof host_addr) <= 0) { + if (inet_pton(af, name, host_addr) <= 0) { h_errno = HOST_NOT_FOUND; return (NULL); } @@ -487,7 +492,7 @@ gethostbyname2(name, af) host.h_name = hostbuf; host.h_aliases = host_aliases; host_aliases[0] = NULL; - h_addr_ptrs[0] = (char *)&host_addr; + h_addr_ptrs[0] = (char *)host_addr; h_addr_ptrs[1] = NULL; host.h_addr_list = h_addr_ptrs; if (_res.options & RES_USE_INET6) @@ -617,9 +622,9 @@ gethostbyaddr(addr, len, af) case AF_INET6: qp = qbuf; for (n = IN6ADDRSZ - 1; n >= 0; n--) { - qp += sprintf(qp, "%x.%x.", - uaddr[n] & 0xf, - (uaddr[n] >> 4) & 0xf); + qp += SPRINTF((qp, "%x.%x.", + uaddr[n] & 0xf, + (uaddr[n] >> 4) & 0xf)); } strcpy(qp, "ip6.int"); break; @@ -770,12 +775,12 @@ _gethtent() goto again; *cp++ = '\0'; if ((_res.options & RES_USE_INET6) && - inet_pton(AF_INET6, p, host_addr, sizeof host_addr) > 0) { + inet_pton(AF_INET6, p, host_addr) > 0) { af = AF_INET6; len = IN6ADDRSZ; - } else if (inet_pton(AF_INET, p, host_addr, sizeof host_addr) > 0) { + } else if (inet_pton(AF_INET, p, host_addr) > 0) { if (_res.options & RES_USE_INET6) { - map_v4v6_address((char*)&host_addr, (char*)&host_addr); + map_v4v6_address((char*)host_addr, (char*)host_addr); af = AF_INET6; len = IN6ADDRSZ; } else { @@ -785,7 +790,7 @@ _gethtent() } else { goto again; } - h_addr_ptrs[0] = (char *)&host_addr; + h_addr_ptrs[0] = (char *)host_addr; h_addr_ptrs[1] = NULL; host.h_addr_list = h_addr_ptrs; host.h_length = len; @@ -859,7 +864,7 @@ struct hostent * _gethtbyname(name) const char *name; { - extern struct hostent *_gethtbyname2 __P((const char *, int)); + extern struct hostent *_gethtbyname2(); struct hostent *hp; if (_res.options & RES_USE_INET6) { diff --git a/resolv/inet_ntop.c b/resolv/inet_ntop.c index 71db06d845..3b5795f349 100644 --- a/resolv/inet_ntop.c +++ b/resolv/inet_ntop.c @@ -29,6 +29,12 @@ static char rcsid[] = "$Id$"; #include #include "../conf/portability.h" +#ifdef SPRINTF_CHAR +# define SPRINTF(x) strlen(sprintf/**/x) +#else +# define SPRINTF(x) sprintf x +#endif + /* * WARNING: Don't even consider trying to compile this on a system where * sizeof(int) < 4. sizeof(int) > 4 is fine; all the world's not a VAX. @@ -84,7 +90,7 @@ inet_ntop4(src, dst, size) static const char fmt[] = "%u.%u.%u.%u"; char tmp[sizeof "255.255.255.255"]; - if (sprintf(tmp, fmt, src[0], src[1], src[2], src[3]) > size) { + if (SPRINTF((tmp, fmt, src[0], src[1], src[2], src[3])) > size) { errno = ENOSPC; return (NULL); } @@ -170,7 +176,7 @@ inet_ntop6(src, dst, size) tp += strlen(tp); break; } - tp += sprintf(tp, "%x", words[i]); + tp += SPRINTF((tp, "%x", words[i])); } /* Was it a trailing run of 0x00's?
